Bonito or “katsuo/鰹” in Japanese are extensively caught by fishermen from Numazu, Shimizu, Yaizu and Omaezaki Harbors (all Shizuoka Prefecture). The main fishing areas are Shizuoka, Mie, Kochi & Miyazaki Prefectures.
It is also called “katsu” (Tohoku Region), “Honkatsuo” (Kyushu Island), “Magatsuo” (Shikoku and Kyushu Islands. N.B.: the same name designates another fish in other parts of Japan!), “Suji” (Yamaguchi & Wakayam Pref.).
It appears on the markets early Spring~Autumn as “sho gatsuo” (first bonito in Spring) and “modori gatsuo” (return bonito end of Autumn).
They are traditionally line-caught but nets have been used extensively in recent years.

It can be appreciated raw, as sashimi with its skin or without it, preferably served with a saucer of soy sauce (shoyu) mixed with thin slices of fresh garlic, or with wasabi, a touch of lemon and shoyu,

or as nigiri topped with grated fresh ginger a thin slice of garlic, unless you prefer grated fresh ginger with chopped thin leeks.

The same is done with lightly grilled/aburi (or tataki) bonito as sushi nigiri.

Another very popular way to eat it that will please Europeans and North Americans alike, is “tataki”.

The fish is first seared/grilled over charcoal until it is lightly cooked on the whole outside then plunged into iced water to stop it from cooking any longer. It is then cut into large slices and served with freshly chopped garlic and thin leeks, “shiso” leaves (perilla/beefsteak plant) and wasabi.

Note 1: in restaurants specify whether you want the skin or not when ordering sashimi.

Note 2: the same fish is a staple food in Sri Lanka where it is first smoked and then prepared as soup or curry!

It is one of the most versatile fish in Japan.
It can be appreciated in many ways:
As a simple donburi/on a bowl or rice at home (see above picture),

Lightly seared and served as carpaccio,

as bogata sushi/whole fish stuffed with sushi rice,

as oshizushi/pressed sushi,

but my favorite is probably as zuke/marinated in soy sauce, mirin, sake, etc. before being served with a slice of garlic!
